USN-5941-1: Linux kernel (KVM) vulnerabilities

It was discovered that the Upper Level Protocol ULP subsystem in the Linux kernel did not properly handle sockets entering the LISTEN state in certain protocols, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service system crash or possibly execut...

SUSE CVE-2014-5146

Certain MMU virtualization operations in Xen 4.2.x through 4.4.x before the xsa97-hap patch, when using Hardware Assisted Paging HAP, are not preemptible, which allows local HVM guest to cause a denial of service vcpu consumption by invoking these operations, which process every page assigned to ...

SUSE CVE-2014-5149

Certain MMU virtualization operations in Xen 4.2.x through 4.4.x, when using shadow pagetables, are not preemptible, which allows local HVM guest to cause a denial of service vcpu consumption by invoking these operations, which process every page assigned to a guest, a different vulnerability tha...

SUSE CVE-2014-8594

The dommuupdate function in arch/x86/mm.c in Xen 4.x through 4.4.x does not properly restrict updates to only PV page tables, which allows remote PV guests to cause a denial of service NULL pointer dereference by leveraging hardware emulation services for HVM guests using Hardware Assisted Paging...

SUSE CVE-2014-9030

The dommuupdate function in arch/x86/mm.c in Xen 3.2.x through 4.4.x does not properly manage page references, which allows remote domains to cause a denial of service by leveraging control over an HVM guest and a crafted MMUMACHPHYSUPDATE...

SUSE CVE-2017-5925

Page table walks conducted by the MMU during virtual to physical address translation leave a trace in the last level cache of modern Intel processors. By performing a side-channel attack on the MMU operations, it is possible to leak data and code pointers from JavaScript, breaking ASLR...

SUSE CVE-2017-12188

arch/x86/kvm/mmu.c in the Linux kernel through 4.13.5, when nested virtualisation is used, does not properly traverse guest pagetable entries to resolve a guest virtual address, which allows L1 guest OS users to execute arbitrary code on the host OS or cause a denial of service incorrect index...

SUSE CVE-2019-2182

In the Android kernel in the kernel MMU code there is a possible execution path leaving some kernel text and rodata pages writable. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation...

SUSE CVE-2021-38198

arch/x86/kvm/mmu/pagingtmpl.h in the Linux kernel before 5.12.11 incorrectly computes the access permissions of a shadow page, leading to a missing guest protection page fault...
